All that is necessary to be a NBC is to have ONE US citizen parent OR be born in the United States. Obozo's mother was an American citizen by birth as was/is Cruz's mom. Having been born in Vancouver therefore does not diminish his status. The rest of us are moving on. You can join us or stay where you are if Cruz is the nominee. I understand the idea of voting one's conscience, beliefs and principles. I refused to support Romney for reasons a LOT more important than where he was born or whether his father (born in Mexico) was ever naturalized after his parents moved to Mexico in an apparent attempt to abandon US citizenship over the federal ban on polygamy as a condition of Utah's admission to the Union.
The Constitution of the United States is the Constitution of the United States whatever any of us might prefer. It does not matter that some obscure Swiss political philosopher expressed his academic OPINION as to "the law of nations" years before the Constitution was written.
It does not matter that Michigan Senator Jacobs (?) the US Senate sponsor of the 14th Amendment wrote in a private letter to a friend in saying that the amendment was only meant to effect citizenship rights of freed former slaves. What matters and mattered is the actual Constitutional text both as originally ratified and as amended by Amendment XIV. There is NO AMBIGUITY. In the absence of ambiguity, there is no occasion for courts or anyone else to ignore the wording to interpret the wording as what one might prefer the Founding Fathers and authors of Amendment XIV had written and enacted rather than what they actually wrote and enacted.
Hence, Cruz is quite eligible for POTUS as a NBC as was Obozo before him and McCain (born in Panama) and the man I have hated most in American politics: Lowell P. Weicker, Jr., (born in Paris while his citizen parents were there on business).
You are, of course, entitled to your opinion and to act accordingly. I confess that I am a LOT more concerned about baby-killing, perversion posing as "marriage," gun grabbing, the exporting of blue collar jobs, etc., etc., etc., ad infinitum, ad nauseam, but, hey, that's just me.
You are right, Mr Laxalt is free to do as he likes. His constituents don’t seem happy with his decision. Quite a few of them as a matter of fact.
